Matter Basics
Anything that has mass and takes up space
What is matter?
The amount of matter in an object
What is mass?
What is a physical property?
A change of matter in which the identity of the substance does not change
What is a physical change?
What is the law of conservation of mass?
The three states of matter
What are solid, liquid, and gas?
The gravitational pull on the mass of an object
What is weight?
The ability of some materials to attract certain metals
What is magnetism?
A change of matter in which the substances that make up matter change into other substances with different physical and chemical properties
What is a chemical change?
What is a precipitate?
A state of matter with particles locked in place that vibrate back and forth; has a definite shape and definite volume
What is a solid?
The amount of space a sample of matter occupies
What is volume?
Mass per unit of volume (how closely particles are packed together); calculated using mass x volume
What is density?
An example of a physical change
What is dissolving, change in state, or [other approved answer]?
A type of change in matter that usually cannot be reversed
What is a chemical change?
A state of matter with particles that flow over one another; has an indefinite shape and a definite volume
What is a liquid?
The ability of one substance to dissolve in another substance
What is solubility?
A characteristic of a material that you can observe as it reacts with or changes to a different substance
What is a chemical property?
An example of a chemical change
What is burning, exploding, spoiling, rotting, or [other approved answer]?
A chemical reaction that produces glucose when plants, phytoplankton, or other organisms are exposed to sunlight
What is photosynthesis?
A state of matter with particles that move fast and are very far apart; has an indefinite shape and volume
What is a gas?
The temperature at which a liquid boils
What is boiling point?
An example of a chemical property
What is flammability, oxidation, ability to rust, or spoiling/rotting?
The only sure sign of a chemical change
What is formation of a new substance?
Property of matter that is always conserved during physical and chemical changes
What is mass?
